oligodendroglia

 [ol″ĭ-go-den-drog´le-ah]
1. the non-neural cells of ectodermal origin forming part of the adventitial structure of the central nervous system.
2. the tissue composed of such cells.

ol·i·go·den·drog·li·a

(ol'i-gō-den-drog'lē-ă), This word is grammatically singular. Avoid the mispronunciation oligodendrogli'a.
One of the four types of glia cells (the other three being macroglia or astrocytes, ependymal cells, and microglia) that, together with nerve cells, compose the tissue of the central nervous system. Oligodendroglia cells are characterized by variable numbers of veillike or sheetlike processes that are each wrapped around individual axons to form the myelin sheath of nerve fibers in the central nervous system (compared with Schwann cells in the peripheral nervous system); forms myelin in the central nervous system, and accordingly are more numerous in white matter than in gray matter.
Synonym(s): oligodendria

oligodendroglia

(ŏl′ĭ-gō-dĕn-drŏg′lē-ə, ō′lĭ-)
n.
Neuroglia consisting of cells similar to but smaller than astrocytes, found in the central nervous system and associated with the formation of myelin.

Ganglioglioma (GG) is a type of rare neuroepithelial tumor of the central nervous system (CNS) and accounts for about 0.4% to 2% of all CNS tumors.1 It contains ganglion cells and neoplastic glial (astrocytic or oligodendroglial) elements pathologically.2 GG is considered as a common cause of tumor-related refractory epilepsy besides other low-grade gliomas, especially in patients younger than 30 years.3 It is reported that GGs accounts for about 40% of all epileptogenic tumors and temporal lobe gangliogliomas are almost always found to show epileptogenicity.4,5 Given the low incidence of GG, risk factors for preoperative epileptic seizure and postoperative outcome are still controversial.
The low initial plating density of dissociated cells was meant to favour the growth of astrocytes with only a very little oligodendroglial and microglial cells contamination.

The possibility that different cell types maybe involved in stages of transport of JCV from archetypal sites of infection to oligodendroglial cells is consistent with the concept that recombination of NCCR sequences from the archetype to the PML-like pattern may itself occur in stages.
